AIMS:
In the present study we investigated the cellular uptake of doxorubicin (DOX) and cytotoxic LHRH analog AN-152 (AEZS-108, zoptarelin doxorubicin) on human UM cell lines (OCM3) and its DOX resistant form OCM3DOX320 by confocal laser scanning microscopy. The LHRH receptor expression was characterized by RT-PCR and immunocytochemistry.
RESULTS:
We were able to establish a new, stable and DOX resistant human UM cell line OCM3DOX320. Our results demonstrated the expression of splice variants and isoforms of receptor for LHRH in OCM3 UM cell line and its doxorubicin resistant form OCM3DOX320. It has been revealed by MTT assay that AN-152 inhibited cell proliferation in a dose dependent manner in OCM3DOX320 cells. Furthermore, receptor-mediated uptake of AN-152 was demonstrated using confocal laser scanning microscopy in both cell line.
CONCLUSIONS:
Our results suggest that the antiproliferative effect of AN-152 can be detected even if only LHRH receptor isoforms are expressed. Our study also demonstrates the LHRH receptor-mediated uptake of AN-152 in DOX resistant OCM3DOX320 cells. Our experiments provide new insights into a potential targeted therapy of UM and give further details about the accumulation of AN-152 in hormone-independent DOX-resistant cells expressing splice variants of the LHRH receptors.
